Hi,
I set up the same system this afternoon. At first, my system got stuck in the bios. I should press DEL or F2 but no reaction. Bios Flashback helped. I have the same board as you mentioned but my bios file is called TGB550PS.CAB Are you sure I selected the right bios?

Everything went smoothly for me, including the bios update and switching off the useless colour orgy around the case. I am very satisfied.

Did you have the box switched off for the BIOS flashback? I also did it wrong the first time. And otherwise the CLR BIOS jumper on the board times with the system switched off with a screwdriver for 5 sec. greetings fieryjack
